I would have liked to have you in the room.

Also, with Luca's new series we discussed some scenarios which can happen WRT to I2C address conflicts. Maybe you could comment on them, too? As I read the old thread, you have a hardcoded aliases using "ti,i2c-bridge-maps". This means you can't have own DTSI files for e.g. add-on modules, do I get this correctly?
